PHARMACODYNAMICS: Use the graph to answer the following. Which curve best describes percentage binding to its receptor as the concentration of a partial agonist is increased from low to very high levels? percent of madmum 120 100 curve e BO 60 40 20 O curve c O curve d O curve a O curve b A -6 0 -10 -B log dose N Use the graph to answer the following question. This graph shows an an endogenous receptor agonist system in which a drug is being added. Line A indicates no drug. Increasing drug is observed from line B (low drug concentration) to line E (high drug concentration). What type of agonist/antagonist is the drug? (Hint: focus on lines A, B and C D and E can occur but weren't specifically discussed for this type of agonist/antagonist.) % of maximal effect ECSO CA ECO (8) EOS (G) 008) RD Log [Agonist] M O competitive antagonist O non-competitive antagonist O non-receptor antagonist O chemical antagonist
